Description

The present invention relates to a cosmetic for massage, and more particularly to a cosmetic having a good base thickness and spread during use, can continuously give appropriate resistance to the skin, and has good washability.

Massage is an action that is expected to have the effect of improving blood and lymph circulation by rubbing the skin with the palms and fingers. The massage cosmetics are cosmetics that can be applied on the skin during massage to give an appropriate frictional force, resulting in a more effective and comfortable feeling of use.

Conventionally, massage cosmetics have been used in which a large amount of oily components such as liquid oil and solid balm are blended for the purpose of reducing frictional force. However, such oily massage cosmetics have problems that they feel sticky during and after use, and oil remains on the skin after use (Patent Document 1). As a method for solving such a problem, it has been proposed to use a light oil such as silicone, but there is a problem that the viscosity is low and the oil flows or spreads from the skin (Patent Document 2). In addition, water-based massage cosmetics can also be seen because they give a fresh feel. These massage cosmetics include liquid ones and gel-like ones, but have drawbacks such as reduction of frictional force during use and insufficient thickness of the base (Patent Document 3). In addition, there are massage cosmetics containing a high amount of polyhydric alcohol. These massage cosmetics can enhance the blood circulation promoting effect by the warming effect of the heat of hydration of the polyhydric alcohol, but have problems such as heavy spreading, stickiness, and drying (Patent Document 4).

On the other hand, the cream-type massage cosmetics are easy to apply and can give an appropriate moisturizing feeling after the treatment. However, if a large amount of solid oil or paste oil is added in order to give the base sufficient thickness and give an appropriate frictional force and moisturizing feeling during use, the spread may be too heavy or remain on the skin after use. You may feel sticky. Further, even if the thickness of the base is sufficient at the time of application, the thickness may decrease during use, and it may not be possible to maintain an appropriate frictional force.

The present invention also provides a massage cosmetic containing (D) a carboxyvinyl polymer.

The present invention also provides a massage cosmetic containing (E) arginine.

The massage cosmetic of the present invention is a massage cosmetic having a good base thickness and spread during use, can continuously give appropriate resistance to the skin, and has good washability.

Examples of the sucrose fatty acid ester composed of (A) linear saturated fatty acid having 12 to 18 carbon atoms in the present invention include sucrose laurate, sucrose myristic acid, sucrose palmitate, and sucrose stearate. These components may be used alone or in combination of two or more. From the viewpoint of smoothness of spread, sucrose stearate is preferable.

(A) The content of the sucrose fatty acid ester composed of linear saturated fatty acids having 12 to 18 carbon atoms is preferably 1.0 to 5.0% by weight, more preferably 1.0 to 5.0% by weight, based on the massage cosmetics. It is preferably 1.5 to 3.0% by weight. If it is less than 1.0% by weight, the stability over time may be poor. On the other hand, if it exceeds 5.0% by weight, the massage cosmetic may become hard and the spread may become heavy.

The (B) tetravalent or higher polyhydric alcohol of the present invention is a compound having four or more alcoholic hydroxyl groups in the molecule. For example, there are polyglycerins such as diglycerin and triglycerin, and sugar alcohols such as maltose, maltitol, xylitol, erythritol, and sorbitol. These components may be used alone or in combination of two or more. Diglycerin is preferred from the standpoint of base thickness.

(B) The content of the polyhydric alcohol having a valence of 4 or more is preferably 1.0 to 15.0% by weight, more preferably 3.0 to 8.0% by weight, based on the massage cosmetics. .. Within this range, it is possible to obtain a massage cosmetic having a certain thickness during massage without being heavy in spreading.

The (C) diisostearyl malate of the present invention is a diester of malic acid and isostearyl alcohol. It is a highly viscous oil and can give a rich feel without stickiness. As commercially available products, for example, NIKKOL DISM (manufactured by Nikko Chemicals Co., Ltd.), Cosmol 222 (manufactured by Nisshin Oillio Group Co., Ltd.), and High Marate DIS (manufactured by Higher Alcohol Industry Co., Ltd.) can be used.

The content of (C) diisostearyl malate is preferably 1.0 to 20.0% by weight, more preferably 3.0 to 8.0% by weight. If it is less than 1.0% by weight, it may not be possible to obtain an appropriate weight at the time of use. On the other hand, if it exceeds 20.0% by weight, it may become sticky during rinsing or sticky after washing.

The oily component used in the present invention is not particularly limited, and corresponds to hydrocarbons, fats and oils, waxes, synthetic esters, silicones, fatty acids, higher alcohols and the like. For example, squalane, mineral oil, vaseline, paraffin, microcrystallin wax, olive oil, almond oil, macadamia nut oil, meadowfoam oil, triethylhexanoin, beeswax, lanolin, carnauba wax, candelilla wax, jojoba seed oil, cetyl palmitate, myristine. Octyldodecyl acid, neopentyl glycol diisononanoate, cetyl ethylhexanoate, isononyl isononanoate, dimethicone, phenyltrimethicone, cyclomethicone, stearic acid, isostearic acid, myristic acid, cetanol, stearyl alcohol, behenyl alcohol, cetostearyl alcohol, cholesterol, etc. Can be mentioned.

The content of the oily component containing (C) is preferably 35.0 to 65.0% by weight, more preferably 40.0 to 60.0% by weight. If it is less than 35.0% by weight, the thickness of the base at the time of use may be insufficient. On the other hand, if it exceeds 65.0% by weight, an oil film may remain during rinsing or the stability over time may be poor.

The content of the (D) carboxyvinyl polymer of the present invention is preferably 0.05 to 1.0% by mass, more preferably 0.1 to 0.6% by mass, based on the cosmetic for massage. If the content is less than 0.05% by weight, it becomes impossible to perform a massage that catches the skin, and if it exceeds 1.0% by weight, slippery or sticky occurs, and smoothness cannot be obtained.

The content of (E) arginine is preferably an amount in which the pH of the massage cosmetic is 5.5 to 8.0, and more preferably an amount in which the pH is 6.0 to 7.5. If the pH of the massage cosmetic is less than 5.5 or more than 8.0, the stability over time may be impaired.

Basic compounds other than arginine used as a neutralizing agent for carbomer include sodium hydroxide, potassium hydroxide, calcium hydroxide, 2-amino-2-methyl-1,3-propanediol, and 2-amino-2-. Examples thereof include methyl-1-propanol, monoethanolamine, diethanolamine, triethanolamine and the like. Although it is possible to contain these, the appearance of the cream is better when arginine is used.

The massage cosmetic of the present invention is an oil-in-water cream-like massage cosmetic. In addition, there are no restrictions on the site of use, and it can be used as a massage cosmetic for the face and body, but from the viewpoint of usability, the use for the face is preferable.
